My short operational definition of a cluster is collection of
independent systems (motherboards) that communicate
over a private network/interconnect, none of which
are dependent on the other for operating, with
excetion of the head/master/gateway node.
Under this definition, a multi-core node is not a cluster
nor is any design whose operation is dependent
upon shared memory between nodes, even though the
nodes are separate systems. Of course this is my
definition.
BTW, I believe the following is also used:
N=nodes
P=cores/processors per node
P>=N = cluster
N<P = constellation
